  1. 1. Competition in Public Transport : Essays on competitive tendering and open-access competition in Sweden

    Author : Andreas Vigren; Svante Mandell; Jan-Eric Nilsson; Nash Nash; Chris Nash; Statens väg- och transportforskningsinstitut; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Public transport; Contract; Tender; Bus; Economic efficiency; Competition; Location; Transport operator; Depot transp ; Impact study; Railway; Line transp ; 02 Road: Economics; 02 Road: Economics; 111 Road: Public transport; 111 Road: Public transport; J13 Railway: Economics; J13 Railway: Economics; Public Transport; Tendering; Procurement; Cost efficient; Open access competition; Transportvetenskap; Transport Science;

    Abstract : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. READ MORE

  2. 2. Making Equity in Public Transport Count

    Author : Isak Rubensson; Yusak Susilo; Oded Cats; Karst Geurs; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Subsidies; Fare-schemes; Accessibility; Crowding; transport justice; Equity; Distribution; Gini index; Lorenz curves; Customer satisfaction; Service quality; Preferences; Reliability; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

    Abstract : Political and public focus on equity and justice outcomes of public policies is on the rise all over the world. Equity is both philosophically motivated and often decreed by law and in planning directives to be monitored when policies are changed, however oftentimes these equity assessments are vague, qualitative and carries low weight in policy decision processes.

    Abstract : It is agreed that greenhouse gas (GHG) emissions from energy and transport systems must be reduced. Technical means exist to reduce GHG emissions from these sources. However, these emission-reduction measures are not implemented to a high enough degree. READ MORE
